Description

  The present invention relates to a portable electric lamp.

  In recent years, due to the frequent occurrence of large earthquakes and abnormal weather, demand for portable electric lights and batteries has increased due to the necessity of preparing for disasters.

  In the event of a power outage due to a disaster or nighttime condemnation, portable lights such as flashlights and lanterns must be kept at home, and batteries that are compatible with these devices must also be kept together. Even if a battery is bought and always available, the battery is often consumed without a disaster for several years, and it is often lost. In addition, even if the battery is always available, the size may not match the battery used for the portable electric light that is also available, and the instrument may not be used.

  In order to solve such problems, it is only necessary to use different sizes of batteries in common with a single portable light, but when considering the method, one is a battery case that can store batteries of different sizes. , Such that at least one side wall having an electrode can move in the longitudinal direction in accordance with the length of the battery, and the bottom plate moves up and down in conjunction with the movement of the side wall, and a battery case corresponding to different battery sizes It is possible to easily apply different types of batteries so that they can be used interchangeably (for example, Patent Document 1).

  In addition, as a portable electric light product, it is possible to store different types of batteries in the battery case of the main unit at the same time, and by rotating the changeover switch outside the main unit battery case, it is possible to select the use of multiple types of batteries Electric lamps and the like are known (for example, Patent Document 2).

Japanese Patent Laid-Open No. 11-204091 JP 2007-12398 A

  When a battery case corresponding to a different battery size is applied to a portable electric lamp as in Patent Document 1, the battery case must be opened and replaced every time the battery size is changed. It is difficult to install batteries in the dark, and only one type of battery can be inserted, so it can be said that there is little battery maintenance in case of a disaster. In addition, a product of a type in which a plurality of different types of batteries as in Patent Document 2 are simultaneously stored in a battery case can be provided with a plurality of batteries in a battery storage unit, so that it has excellent preparedness for disasters. The mechanism for the individual connection leads corresponding to each type of battery, the switching lead that selectively conducts to the connection leads of each battery, and the switch knob is complicated and requires many parts for the switching function of the battery used. Yes. Further, in Patent Document 2, since the switch is behind the instrument, it is necessary to look into the back when operating the switch, and it may be difficult to know which battery is used among the stored batteries.

The present invention relates to a portable light that allows different sizes of batteries to be used in common by a single portable light, regardless of the type of battery that is always available at home in preparation for disasters, etc. While the structure can always hold multiple different types of batteries in the housing, the switch function of the multiple types of different batteries makes it easier to understand the battery being used while improving operability, and the structure is simpler than the conventional one. The purpose is to provide a wide range of portable electric lights that are cheap and convenient for consumers.

  In order to solve the above-mentioned problems, the portable electric lamp of the present invention is configured such that a light emitting unit incorporating a light source and a battery storage unit are rotatably fitted, and a positive electrode and a negative electrode are connected to the light emitting unit to supply power to the light source. A plurality of batteries have a lead in the battery housing part, and the rotation center axis of the light emitting part and the battery housing part is substantially parallel to the axis connecting the positive electrode and the negative electrode of the battery. Aligned in the same direction, and the axis of the battery and the rotation center axis of the light emitting unit and the battery storage unit are respectively stored and arranged in a separated positional relationship, and according to the rotation of the light emitting unit and the battery storage unit, It is configured to selectively switch between conduction with any one of a plurality of stored batteries and non-conduction with any of the batteries.

  In other words, the connection leads for obtaining the voltage from the battery facing one terminal of the battery while storing a plurality of batteries in the battery storage part are in the same direction according to the rotation of the light emitting part and the battery storage part. It moves between the same polarities of a plurality of different types of batteries stored with good characteristics, and constitutes a switch function that switches between turning on and off by selecting a battery to be used.

  According to the present invention, since a plurality of and different types of batteries can be stored and used, it can be conveniently turned on with existing batteries that are always available in an emergency. In addition, since a plurality of batteries can be stored and kept in the battery storage unit, preparation for a disaster or the like is complete. Furthermore, using a connection lead or the like that is a normal component in a portable electric light, and a switch function by turning the light emitting part and the battery storage part of the portable electric light, it does not have a switch knob or the like outside the device, Since there is no need for a separate mechanism and parts such as a special switching lead and an external switch knob, which are conventionally required for switching, the structure is simple and inexpensive. In addition, the switch can be turned on and off by rotating the device body, so it is not necessary to look into the back of the device body, and it can be operated naturally, and the large part of the body can be gripped and rotated firmly. So it is easy to use and easy to use in the dark.

  More preferably, in the battery housing portion, the battery is electrically connected to one terminal of the positive electrode or the negative electrode of each of the plurality of stored batteries, and the same polarity of either the positive electrode or the negative electrode of all the stored batteries is made into a single terminal. An aggregated aggregate terminal is arranged, and the light emitting unit is electrically connected to the aggregate terminal with a single aggregate terminal connection lead that contacts and conducts with the aggregated terminal to supply power to the light source, and with the opposite polarity. A single battery connection lead facing a battery electrode opposite to the battery electrode to be connected, and the single battery connection lead is electrically connected to one terminal of the same polarity of a plurality of stored batteries, or When configured to be non-conducting with any battery, the connection lead arranged in the light emitting unit is only one for positive and negative, and the function of the switch to each battery is not arranged for each battery. Can play more The can be simplified.

  Also, in the vicinity of the boundary between the light-emitting part and the battery compartment that can be seen on the exterior of the portable lamp body, the symbol for the name of the battery or the types of batteries that are stored in the battery compartment in either the light-emitting part or the battery compartment. The other light emitting part or battery storage part that displays the battery type is not displayed, but the other light emitting part or battery storage part displays the alignment mark with the battery type display, and the light emitting part and the battery storage part are rotated. When the indication of the battery type is aligned with the mark of the battery type, the corresponding battery corresponding to the indication of the battery type is in a conductive state with the light source, and each indication is performed. Among these, the selection of the battery to be used can be easily discriminated from the appearance, and it becomes easier to use.

  Also, there is an intermediate part between the light emitting part and the battery accommodating part, the battery accommodating part is fixedly fitted to one end of the intermediate part, the light emitting part is located at the opposite end of the intermediate part, and the light emitting part and the battery accommodating part are accommodated. The center of the intermediate part is positioned so that the positional relationship in the direction of the rotation center axis of the part is fixed, the rotation is freely fitted, and the electrical connection between the light emitting part and the battery storage part is possible. Has a hole corresponding to an electrical contact or a relay conduction means, and has a spring-like member that generates a contact pressure in contact with either one of the positive electrode and the negative electrode of the stored battery. The one end of the other battery electrode not in contact with the spring member is pressed against the surface of the one end of the intermediate part by the spring pressure of the spring member, and between the positive electrode and the negative electrode of the battery electrode. The position of the connected axial direction is kept almost constant on the surface of one end of the intermediate part. When configured in the state, the spring pressure for securing the contact pressure to each electrical contact is not directly applied to the light emitting part, so that the light emitting part has good rotation and there is a risk of wear of parts of the rotating sliding part. Less durability. In addition, there is an effect that the rotational operation force of the light emitting unit becomes constant regardless of whether a battery is inserted or not. In addition, since the position of the battery electrode in contact with the battery connection lead arranged in the light emitting portion is aligned at one end of the intermediate component, the battery connection lead can be electrically connected to the battery of any size under the same conditions.

  Further, in the light emitting part, the battery connection lead facing the battery electrode opposite to the battery electrode through which the aggregate terminal is conductive can move up and down in the direction along the axis connecting the positive electrode and the negative electrode of the battery, When configured to be pressed with spring pressure toward the battery's electrode terminal, it is stable to any battery while flexibly responding to differences in battery electrode height caused by differences in battery manufacturers and manufacturing variations. Contact pressure can be ensured.

  In addition, the battery connection lead that is pressed with a spring property in the direction of the electrode terminal of the battery and that is away from the rotation center axis of the light emitting unit and the battery storage unit, A protrusion that protrudes in the direction of the component is integrally formed, and a surface of the intermediate component adjacent to the light emitting portion is a circle of a rotation locus circle of the protrusion generated by the rotation of the light emitting portion and the battery storage portion. On the circumference, there are at least the number of types of storage of the battery, and the protrusion is fitted into or out of the recess by turning the light emitting unit and the battery storage unit. If any of the plurality of batteries is in a conductive state with the light source and lights up at the position where the protrusion fits into the part, the corresponding battery to be used when rotating the light emitting part and the battery storage part Stop at a location with mobility in both directions of rotation Can be, the lighting state is strong even in a stable vibration, it is also safe not carry this portable electric lamps. In addition, by making it possible to rotate on both sides, it becomes possible to quickly switch to the battery to be used.

  In addition, when the contact surface of the battery connection lead with the battery terminal has a long, substantially rectangular shape extending from the rotation center axis of the light emitting part and the battery storage part toward the outer peripheral direction, Even if the distance between the contact point of each battery electrode from the rotation center of the light emitting unit and the battery storage unit varies depending on the arrangement, the battery connection lead hits the contact point of each battery. In other words, the battery can be arranged in any position, and can be made into a product that is small, resource-saving, easily available, and easy to carry by effectively using space.

  More preferably, the aggregate terminal in the battery housing portion is disposed on a surface adjacent to the light emitting portion, and the arrangement position is a position deviated from the rotation center axis of the light emitting portion and the battery housing portion, and correspondingly contacts with each other. If the contact surface of the aggregate terminal connection lead on the light emitting part side is wide or substantially circular corresponding to the range of the circle locus of the aggregate terminal, the position of the aggregate terminal deviates from the center of rotation as described above. As a result, the battery can be arranged freely, and the space can be effectively used to make the product compact, resource-saving, easy to use, and easy to carry.

Further, the intermediate part and the light-emitting part are fitted in such a manner that the positional relation in the rotation central axis direction of the light-emitting part and the battery housing part is fixed and the rotation is freely fitted. If you have a band-shaped part that wraps together so as to straddle and a handle shape is formed on a part of the band-shaped part, while holding the band-shaped part and handle part located on the outer periphery of the device with one hand, When turning the light emitting part with one hand to perform a switch operation or twisting the battery housing part for battery replacement, a force is easily applied, and the operability can be further improved. In addition, the handle shape makes it easy to carry out in an emergency and has good portability.

  As shown in FIG. 4 and FIG. 5, an intermediate part 3 is arranged between the light emitting part 1 and the battery storage part 2, and the battery storage part 2 is fitted to one end of the intermediate part 3 by a bayonet method with a removable specification. On the other hand, the light emitting unit 1 is in contact with the opposite end of the intermediate part 3 and is integrally wrapped by the handle right piece 4 and the handle left piece 5 so as to straddle the outer peripheral side of the light emitting part 1 and the intermediate part 3. The ribs 4a and 5a formed on the inside of the handle right piece 4 and the handle left piece 5 are fitted on the outer peripheral sides of the light emitting unit 1 and the intermediate part 3, so that the light emitting unit 1 and the battery housing unit 2 While the positional relationship in the direction along the rotation center axis 6 does not move, rotation is possible.

  In the battery housing portion 2, a single 1 type dry battery 7 a, a single 2 type dry battery 7 b, an AA type dry battery 7 c, and a single 4 type dry battery 7 d are arranged as a plurality of batteries, the rotation center shaft 6, the positive electrode of the battery, The polarities of the batteries 7a to 7d are all stored in the same direction with the positive electrode facing the light emitting unit 1 side, with the axis connecting the negative electrodes in parallel. In the drawing, each battery is indicated by a two-dot chain line.

A battery spring 8 is installed for each battery as a spring-like member for generating contact pressure at the negative electrode ends of the batteries 7a to 7d, and further, as shown in FIG. And the aggregation terminal 10 that is connected to the negative electrode terminal plate 9 by the fixing screw 25 and extends to the surface adjacent to the light emitting unit 1.

  In the first embodiment, a plurality of different types of batteries are used one by one. However, depending on the consideration of the lighting voltage of the light source and the length of the battery life, each type of battery can be divided into a positive electrode and a negative electrode. A plurality of them may be stored in series in the axial direction.

  As shown in FIG. 5 and FIG. 6, the battery housing portion 2 has the inner projecting portions 2 a and 2 b for bayonet-type fitting and the battery housing portion in a closed state at the fitting portion with the intermediate part 3. As shown in FIG. 5 and FIG. 7, the outer peripheral part of the intermediate part has a locking part 3 a, 3 b and a semi-circular protrusion part 3 c. The inner convex portions 2a and 2b of the battery housing portion are fitted into the battery housing portion and are fitted by turning the battery housing portion clockwise. When the inner convex portions 2a and 2b hit the circumferential ends of the hook portions 3a and 3b, the semicircular convex portion 2c on the battery housing portion side gets over the semicircular convex portion 3c on the intermediate component side and is locked. The battery storage unit 2 is in a fixed position while being detachable. In addition, the locking force by the semicircular convex portions 2 c and 3 c is set to be stronger than the rotational operation force of the light emitting unit 1 and the battery storage unit 2.

  In the light emitting unit 1, a light source 12 and a circuit board 13 associated therewith are arranged in a cylindrical case 11 in which a part in contact with the intermediate component 3 and a side surface of the light emitting unit are integrally formed, and a positive electrode cord 14 is provided to supply power to the circuit board 13. And the negative electrode cord 15 is arranged. The positive electrode cord 14 is connected to a single battery connection lead 16 facing the positive electrode of each battery housed in the battery housing portion 2, and the negative electrode cord 15 is for a single aggregation terminal facing the aggregation terminal 10. It is connected to the connection lead 17. The contact point between the aggregation terminal 10 and the aggregation terminal connection lead 17 is located near the center near the rotation center axis 6, while the battery connection lead 16 is located away from the rotation center axis 6, and the light emitting portion With the rotation of 1, it moves so as to draw a rotation locus circle.

  In front of the light source 12, a translucent front cover 18 fitted to the cylindrical case 11 is disposed. The cylindrical case 11 may be made of either an opaque material or a translucent material. In the case of an opaque material, the cylindrical case 11 is a light emitting type product that emits light only in the front direction. In the case of a translucent material, The surface can be processed into satin, or it can be made into a lantern type product that is translucently colored and diffuses light around.

  Moreover, as shown in the external appearance of FIG. 3, in the first embodiment, the dead space of the battery housing portion 2 is narrowed down in a shape substantially along the outer shape of the batteries 7 a to 7 d. When the battery storage unit 2 is removed from the main body and different types of batteries 7a to 7d are inserted, there is an effect that the insertion location can be intuitively understood. There is an advantage that it is easy to put a hand on the dent part during the dynamic operation. In addition, there is an effect of reducing the amount of materials used.

  The above is the schematic configuration of the first embodiment according to the present invention, and the light emitting unit 1 and the battery storage unit 2 are rotatable from the outside of the device. A single battery connecting lead 16 at a position away from the shaft 6 moves on the positive electrode of any of the stored batteries 7a to 7d or on a position outside the battery, and This is a battery selection switch function that enables switching between the conductive state and the non-conductive state.

Hereinafter, along the first embodiment, the main points according to the present invention will be described in more detail. As in the first embodiment, even when a plurality of different types of batteries are all dry batteries, and the batteries are cylindrical and have the same basic shape, the battery connection leads 16 and the aggregate terminal connection leads 17 in the light emitting section 1 are used. It is desirable to design a single battery, and it is possible to handle various types of batteries while suppressing the number of parts. However, for example, although not shown, when the specification can accommodate a completely different type of battery such as a coin-type battery, it may not be possible to use a single connection lead due to the difference in battery terminal shape. is there. In such a case, positive and negative electrode connection leads may be provided for each type of battery.

  Next, in the vicinity of the boundary line between the light emitting unit 1 and the battery storage unit 2 that can be seen in FIG. 1, an indication 19 of the type of battery stored in the battery storage unit 2 is provided on the circumference of the light emitting unit 1. Yes. In the first embodiment, the display positions of the battery type display 19 are arranged such that four types of batteries are arranged at equal intervals of 90 °, and therefore, 90 ° etc. on the circumference of the light emitting unit 1 according to the arrangement order. Displayed at intervals. In addition, a light-off display 20 is made with (OFF) characters between each battery display. Thus, it is convenient to set both sides of the lighting position of each battery to the extinguishing position. On the other hand, as the display on the battery storage unit 2 side, the alignment mark 21 is displayed in the middle of the band of the handle left piece 5. Although it is displayed on the handle left piece 5 instead of being displayed on the battery storage unit 2, the movable unit of the battery selection switch is divided into two (battery storage unit side) including the handle and (light emitting unit side). Therefore, even if the alignment mark 21 is displayed on the handle left piece 5, it is agreed that there is an alignment mark on the battery housing portion side.

  When the light emitting unit 1 and the battery storage unit 2 are rotated and the battery connection lead 16 moves onto the positive terminal of a certain battery, the battery type display 19 corresponding to the certain battery and the alignment mark 21 on the left side of the handle. If it is displayed so that it fits, you can easily select and use the battery you want to use. In addition, since the alignment mark 21 is located at an easy-to-see position on the side of the device body, it can be clearly seen which battery is being used. In the first embodiment, the battery type display 19 and the turn-off display 20 are displayed on the light emitting unit 1 side, but the display on the battery storage unit 2 side and the light emitting unit 1 side may be reversed.

  In the battery type display 19, those that imitate the outer shape of the battery, those classified by the number and size of the grains, and the like are included in the (battery type symbolized). Moreover, in the display 20 of light extinction, nothing may be displayed at the corresponding location, and all positions that are out of the battery type display 19 may be set to the light extinction state. In addition, only the mark 21 is displayed on the light emitting unit 1, and the external shape of the battery storage unit 2 is narrowed down according to the shape of the battery stored inside as in the first embodiment, so that the battery type from the external appearance. When the mark 21 is aligned with the external bulge portion of the corresponding battery, it can be said that it is an agreement with (the battery type is symbolized).

  Next, the intermediate part 3 in FIG. 4 has a configuration in which a hole is formed in the center and electrical contact is made between the light emitting unit 1 side and the battery storage unit 2 side within the range of the hole. The shoulder portion on the positive electrode terminal side of the batteries 7 a to 7 d is in contact with one end of the intermediate component 3, the convex portion of the positive electrode terminal of the battery enters the central hole of the intermediate component 3, and the aggregation terminal protrudes to the end surface of the battery housing portion 2 10 is also configured to enter the central hole so as to come into contact with the light emitting unit 1 side. In addition, when the insertion direction of the stored battery is wrong, the negative electrode side of the battery is in contact with one end of the intermediate part 3, but the intermediate part 3 is merely contacted with the shoulder on the negative electrode side. Since the negative electrode terminal of the battery does not enter the center hole, the reverse connection is prevented.

  A battery spring 8 is installed in each battery as a spring member for generating contact pressure at the negative electrode ends of the batteries 7 a to 7 d in the battery housing portion 2, and is a positive-side convex portion that is not in contact with the battery spring 8. With the peripheral shoulder portion pressed against the surface of one end of the intermediate component 3 by the spring pressure of the battery spring 8, the height in the axial direction connecting the positive electrode and the negative electrode of the convex portion on the positive electrode side is intermediate. It is in a state of being kept almost constant in the central hole of the component 3. That is, multiple battery spring pressures from the negative electrode side are received by the intermediate component 3 and are not directly applied to the light emitting unit 1, and high spring pressure is not directly applied to the light emitting unit 1. In addition, there is less concern about wear of parts of the rotating sliding part, and durability is improved. In addition, there is an effect that the rotational operation force of the light emitting unit 1 becomes constant regardless of whether a battery is inserted or not. In addition, since the position of the battery electrode in contact with the battery connection lead 16 disposed in the light emitting unit 1 is aligned at one end of the intermediate part 3, any size battery can be electrically connected to the battery connection lead under the same conditions. Contact reliability can be improved.

  As described above, even when the position of the battery electrode in contact with the battery connection lead 16 becomes substantially constant, the height from the shoulder portion of the battery positive electrode to the tip of the convex portion varies depending on the battery manufacturer and manufacturing variations. Therefore, it is necessary to flexibly cope with the battery connecting lead 16 part. For example, as for the actual height of the convex part of the commercial product of the dry cell adopted in the first embodiment, 0.8 mm to 1.2 mm for the AA type dry cell and 1.0 mm to 1 for the AA type dry cell. The variation varies from 1.5 mm to 2.2 mm for a 0.7 mm, single 2 type battery, and about 1.5 mm to 2.8 mm for a single 1 type dry battery. In other words, even if the height of the battery electrode is substantially matched using the intermediate part 3 described above, there is a difference in the height of the convex portion of about 2 mm at the maximum in the single-type to single-type batteries, and the battery connection leads 16 It is necessary to cope with the height difference in the part.

  As shown in detail in FIGS. 4, 8, and 9, in the light emitting unit 1, the terminal base 22 is disposed so as to be surrounded by the inner rib of the cylindrical case 11 and move only in the axial direction of the battery. A battery connection lead 16 is integrally fixed to 22, a terminal spring 23 is provided on the opposite side of the battery connection lead 16 installation surface of the terminal base 22, and a spring cover 24 is provided behind the spring, and the spring cover is provided with a fixing screw 25. Is fixed to the cylindrical case 11. In this way, the battery connecting lead 16 is pressed in the direction of the battery pole terminal by the spring pressure of the terminal spring 23, and the contact state with the batteries 6a to 6d of different sizes is stabilized.

Further, both sides in the circumferential direction of the rotation trajectory circle of the battery connection lead 16 projecting toward a part of the terminal base 22 toward the intermediate component 3 and rotating with the light emitting unit 1 and the battery storage unit 2. A V-shaped protrusion 22a having a tapered wall is formed. Although the protrusion is V-shaped here, it may be an R-shaped half-round protrusion or a trapezoidal protrusion with a narrowed tip. The battery connecting lead 16 may have a protrusion on a part of the battery connecting lead, but the battery connecting lead 16 is fixed integrally with the terminal base 22 and moved up and down, so it is also agreed that the terminal base 22 has a protrusion. Although not shown, in order to reduce the number of components, the terminal base 22 is not used, and the battery connection lead 16 itself is used as a leaf spring / conduction lead, and a V-shaped protrusion is formed on a part thereof. Good. When the protrusions are formed using the terminal base 22, it is desirable to use a resin material having a property of being slippery and having excellent wear resistance as the material of the terminal base 22.

  On the other hand, the intermediate part 3 is formed with an annular rib 3d along the circle of the trajectory of the battery connecting lead 16, and eight V-shaped recesses 3e are formed on the annular rib 3d in a shape corresponding to the V-shaped protrusion 22a. Provided. The intervals between the V-shaped dents 3e correspond to the above-described four battery type displays 190 displayed on the external appearance of the device and the four light extinction displays 20 between them, and are set at eight equal intervals. By rotating the light emitting unit 1 and the battery storage unit 2, the V-shaped protrusion 22a is fitted into or out of the V-shaped recess 3e, and the V-shaped projection 22a is fitted into the V-shaped recess 3e. The battery type display 19 or the turn-off display 20 displayed on the exterior of the device is aligned with the alignment mark 21. As described above, the variation in the height of the positive electrode convex portion of the AA to AAA batteries is about 2 mm at maximum, and considering this, the depth of the V-shaped recess 3e and the height of the V-shaped protrusion 22a are preferably Even if the height of the convex portion of the battery positive electrode is changed to 3 mm or more, the V-shaped protrusion 22a is configured to be surely fitted into the V-shaped recess 3e.

  Since the battery connection lead 16 integrated with the terminal base 22 is pressed against the battery pole by spring pressure, when the V-shaped projection 22a and the V-shaped recess 3e are combined, the taper of the V-shaped side wall hits each other to emit light. The rotation of the part 1 and the battery storage part 2 is restricted, and the position can be stopped in the conductive state or the light-off state. When the light emitting unit 1 is rotated by applying a turning torque from this state, the V-shaped protrusion 22a can be again ejected from the V-shaped recess 3e while pushing back the spring pressure of the terminal spring 23 because the tapers are in contact with each other. Thus, the stop of the rotation position at the conduction / extinguishing position can be realized with removability. In addition, when the taper is provided in both rotation directions as described above, it is possible to realize a changeover switch that can be rotated in both directions, and to quickly select a battery to be used.

  Next, as shown in FIG. 7, the contact surface of the battery connection lead 16 with the battery positive electrode convex portion is a rectangular shape extending from the rotation center axis 6 of the light emitting portion 1 and the battery housing portion 2 toward the outer peripheral direction. It is said. In the first embodiment, since it is desired to design the device itself as small as possible, a plurality of different types of batteries are arranged as close to the center as possible in the battery storage unit 2. As a result, the distance from the rotation center axis 6 to the contact point of each battery electrode varies widely. That is, it is difficult for the single battery connection lead 16 to hit all the battery contacts when the light emitting unit 1 and the battery storage unit 2 are rotated. Therefore, the contact surface of the battery connection lead 16 is a rectangle extending from the rotation center axis 6 toward the outer peripheral direction so that the contact is possible regardless of the position of the battery.

  In FIG. 6, the aggregate terminal 10 in the battery housing portion 2 is connected to the negative electrode terminal plate 9 that is in common conduction with the negative electrode of each battery by a fixing screw 25 at the back of the battery housing portion 2, and is adjacent to the light emitting portion 1. The U-shaped tip is hooked on a rib in the battery housing portion 2 and is fixed to a position away from the light emitting portion and the rotation center axis 6 of the battery housing portion 2.

  As described above, in the first embodiment, in order to arrange a plurality of different types of batteries as close to the center as possible in the battery storage unit 2, the aggregation terminal 10 uses the space between the batteries to rotate the center. The shaft 6 is disposed at a remote position. On the other hand, the contact surface of the aggregation terminal connection lead 17 on the light emitting unit 1 side is a metal plate having a wide shape close to a circle corresponding to the range of the rotation locus circle of the aggregation terminal 10. Even if it is away from the shaft 6, it keeps conducting.
