Description

[Detailed Description of the Invention] The present invention relates to a feeding device for paper strips such as continuous memo paper, and in particular, a pair of spools are removably provided inside the casing to facilitate replacement of the paper strips. It uses an electric motor built into the casing to allow it to be drawn out in either forward or reverse directions.

Wrap both ends of the strip of memo paper around the spool, rotate the spool to move the memo paper one by one, and search for the phone number, address, etc. written on the paper, or pull out the blank space of the paper and write in the desired information. Various types of electric telephone number indexers or memorandum devices have been proposed in the past.

All of these have a pair of reduction gear trains arranged around the pinion of the motor output shaft, and are configured to mesh with one of the reduction gear trains during forward or reverse rotation, and are driven by a forward/reverse control mechanism. The system was complicated and prone to failure, and the spool could not be removed, making it inconvenient to replace the paper strip.

In this case, the present invention eliminates all of the above-mentioned drawbacks by simplifying the forward/reverse control mechanism and by making the spool removable.

In other words, in the present invention, the pinion is fixed to the motor output shaft, and an arm supporting the planetary gear is suspended, and the arm moves in the direction of the rotational torque of the pinion, thereby transferring the rotational force of the pinion via the planetary gear. Since the rotational speed is transmitted to one of the reduction gear trains for forward rotation or reverse rotation, the number of parts of the forward and reverse rotation mechanism can be reduced, and the operation is reliable.

Further, inside the casing, a transmission member for frictionally driving the spool is provided between the end shaft of the reduction gear train and the spool retaining shaft, and a manual feeding knob is formed at one end of the spool. Since the other end is formed with a recess that can be engaged with the locking shaft, the spool can be rotated not only automatically by an electric motor but also manually in forward and reverse directions, and moreover, the spool can be removed from the casing. It is removable, making it extremely easy to replace paper.

The present invention will now be described in detail based on illustrated embodiments.

In Fig. 1, reference numeral 1 denotes an exterior casing, and this casing 1 is constructed so as to be able to be divided into an upper casing 1a and a lower casing 1b. A window 3 for seeing through the memo paper (band-shaped paper) 2 is opened.

Further, the upper casing 1a is provided with push buttons 4a and 4b for rotating the winding spool for the memo strip in the normal direction or in the reverse direction.

Note that the window 3 may be integrally provided with a cover made of a transparent plastic plate through which the band-shaped memo paper 2 can be visually recognized, or it may be used as a mere opening to allow necessary information to be written on the memo paper 2. You can also do 7.

On the other hand, a battery storage box 5 with a lid 5a is formed at the bottom of the lower casing 1b, and a battery 6 is stored therein.

Furthermore, a pair of spools 8a, 8a are horizontally suspended inside the casing 1 that sandwiches the see-through window 3.

These spools 8a, 8b have a knob 7 for manual rotation at one end.
a, 7b are formed to protrude from the side of the casing 1, and the other end is removably supported by having a recess 31.31 that engages with a retaining shaft 26.26, which will be described later.

The spools 8a and 8b are used to wind up both ends of the band-shaped memo paper 2, and the memo paper may be a simple blank paper, or may have a background pattern, coloring, or ruled lines. Paper may also be used.

Incidentally, a means for moving the memo strip is incorporated into the casing 1, and this point will be explained below.

As clearly shown in FIGS. 1 and 2, spools 8a and 8b for winding the memo strip 2 and an electric motor (hereinafter simply referred to as motor) 9 are provided in the casing 1, and as shown in FIGS. A forward/reverse control mechanism 10, a pair of reduction gear trains 18a and 18b, a transmission member 28 for winding are disposed between the spool and the motor, and a switch mechanism 11 for controlling the feeding of the memo paper is also installed.

In the present invention, each of the above-mentioned members or circuit elements is arranged so as to be housed in the casing 1 in the most compact manner, as described below.

Incidentally, the board 12 is fixed to the lower casing 1b with a set screw 12b via a mounting piece 12a formed on the edge thereof.

Two bearing plates 13 and 14 are vertically disposed on one side edge of the substrate 12 so as to form a gear storage case having a U-shaped cross section.

The output shaft 9a of the small motor 9 attached to the base plate 12 is introduced inside the bearing plate 14, and a pinion 15 is fixed to the shaft end, and an arm 16 is hung so as to be swingable. Planetary gear 1 that constantly meshes with pinion 15 at the tip
The forward/reverse rotation control mechanism 10 is configured by supporting the normal/reverse rotation control mechanism 7.

Since the arm 16 moves in the rotational direction of the pinion following the rotational torque of the pinion 15, when the motor 9 rotates, the arm 16 moves the planetary gear 17 in the rotational direction. The rotational force of one of the pair of reduction gear trains 18a and 18b arranged around the center is transmitted.

The bearing plate 13 is provided with a pair of stoppers 24, 24 for regulating the swing angle of the arm 16, as shown in FIG.

The reduction gear trains 18a and 18b are mounted coaxially with a first-stage reduction gear 19.19 that meshes with the planetary gear 17 at the tip of the arm when the arm 16 moves in the rotational torque direction. transmission gears 20, 20, and a second stage reduction gear 21.21 that meshes with the transmission gears 20.20.
It consists of

The other end of the shaft 22 of the second stage reduction gears 21, 21 is connected to the bearing plate 1.
It is supported by a bearing part 23 at a position opposite to 3.

This shaft 22 has a pulley 25, and between the pulley 25 and an engagement shaft 26 that engages one end of the spool, and a pool 27 on the 26 side, a winding belt made of an elastic material such as a plastic belt or a rubber belt is connected. is connected to the transmission member 28.28.

The rotation of the motor 9 is transmitted to one of the reduction gear trains 18a, 18a via the planetary gear 17 of the forward/reverse control mechanism 10, and the winding is finally applied to the locking shaft 26 on which the transmission member 28 is applied.
Paper 2 rolled around spoons 8a and 8b by rotating
It is something that brings out the following.

Spool 8a. 8b is supported inside the casing 1 as shown in FIGS. 3, 4, and 6, and has several long grooves 29 in its main body for inserting the ends of the continuous paper 2. One end of the main body is supported by a bearing 30 provided in the lower casing 1b, and the other end forms a polygonal recess 31 that engages with the end of the retaining shaft 26, as described above.

Next, to explain the switch mechanism and circuit relationship that controls the start/stop mechanism of the take-up spool, that is, the reduction gear mechanism, as an example, as shown in FIG. This device incorporates a switch SW, but in the present invention, as described below, this switch is configured to be extremely thin, and the pair of pushbuttons 4a and 4b are
If the memo paper is forwarded, it can be reliably forwarded backwards.

FIG. 8 shows an example of the switch mechanism 11, in which leaf spring type contact members 32, 32 are arranged corresponding to the push buttons 4a, 4b, respectively, and contacts are placed above and below the tips of these contact members 32, 32. 33 and 34 are fixed.

A bent portion is formed at the tip of the contact member 32.32, and the elasticity of the leaf spring tends to always contact the upper contact point 33.

The upper contact 33 is connected to the positive side of the battery 6, the lower contact 34 is connected to the negative side of the battery 6, and the contact members 32, 32 are connected to close both poles of the motor 9.

When one push button 4a is pressed down, the bent part of the right contact member 32 separates from the upper contact 33 as shown by the chain line in FIG. 34, the left pole of the motor 9 becomes negative through the left contact member 32, and the right pole of the motor 9 becomes positive through the lower contact 34 and the right contact member 32, causing the motor to rotate normally.

When the push button 4a is released, the right contact member 32 returns to its original state as shown by the solid line in FIG. 8, and the rotation of the electric motor 9 is stopped.

When the push button 4b is pressed down in the opposite direction, the left contact member 3
2 communicates with the lower contact 34, so that the electric motor 9 is reversed.

In this way, when either of the push buttons 4a or 4b is pressed, whichever of the double-throw switches closes, and the above-mentioned contact and non-contact modes are switched accordingly, and the polarity of the battery relative to the motor is switched. It is.

Since the switch mechanism used in the device of the present invention is constructed as described above, the overall thickness is reduced and the switch mechanism is extremely small. It is possible to store it directly under the

When using the memo paper feeding device of the present invention, the casing 1 is opened, the desired memo paper 2 is wound around the take-up spools 8a and 8b, the casing 1 is closed, and the push button 4a or 4b to feed out the note paper.

FIG. 3 shows the case where the monitor 9 is rotated forward by pressing the push button 4a, and the counterclockwise rotation of the output shaft 9a causes the arm 16 of the forward/reverse control mechanism to move to the right stopper 24. The planetary gear 17 meshes with the first stage reduction gear 19 on the right side, and the reduction gear train 18 a
For winding, the right spool 8a is rotated via the transmission member 28 to wind the paper 2.

In this state, the left reduction gear train 18b is the planetary gear 17
Since the mesh with the spool 8b is about to disengage, the spool 8b is not driven, and only the spool 8b is freely rotated in the rewinding direction due to the movement of the paper 2.

Due to the rotation of the right spool 8a, the paper 2 is moved to the guide plate 35.
Since the paper moves upward, the switch is opened by releasing the push button 4a after feeding out the desired paper portion, and the feeding operation is stopped.

Next, when the rotation is to be reversed, the push button 4b must be pressed, or the polarity of the motor will be reversed by the action of the switch mechanism 11, as explained with reference to FIG. 8, and the rotation will be reversed.

That is, the pinion 15 rotates clockwise, and the rotation of the arm 16 is switched by the rotational torque, and the left reduction gear 18b and the planetary gear 17 mesh, driving the left spool 8b and moving the paper 2 forward. It involves winding in the opposite direction.

If telephone numbers and the like are written on the memo sheet in advance, these telephone numbers can be dynamically retrieved by simply pressing a push button.

Also, if you want to write a normal memo, you can easily pull out the blank space on the memo paper by pressing a button.

When replacing the paper strip 2, open the casing 1, disengage the engagement shafts 26 from the recesses 31 of the spools 8a and 8b, take them out, wrap new paper around the spools, and set them again. , or you can set another spool prepared in advance.

In the embodiment of the present invention, the upper part of the casing 1 is made to protrude greatly to incorporate a date and day of the week indicator 36, and a window hole 37 is provided in the upper surface.

As shown in FIGS. 2, 3, and 7, this indicator 36 has left and right frames 38, 38 horizontally mounted on a common axis, and drums 41, 42 for displaying the month, date, day of the week, etc. 4
3°44 is supported.

As for the date drums, a drum 43 with the 1st date is fixed to the core shaft 39, a drum 42 with the 10th date is fixed to the cylindrical shaft 40, and claws 45 are provided on the sides of both drums. A carrying member 46 is provided so that the date in the 10th place rotates one pitch for each rotation of the date 43.

Therefore, by rotating the dial 47 provided at one end of the core shaft 39, a desired date from 1 to 31 written on the surface of the drum 42, 43 can be displayed through the window hole 37.

Further, a corner changing dial 48 is provided outside the date changing dial 47.

The month display drum 41 is attached to a cylindrical shaft 50 adjacent to the cylindrical shaft of the 10th place date display drum 42, and a ratchet wheel 51 is attached to the side surface of the month display drum 41, which extends upward from the lower casing 1b. It also engages with a stopping claw 52 to prevent the display position from being reversed.

Furthermore, a drum 44 for displaying the day of the week is inserted into the tip of the core shaft 39, and a large number (for example, 14) of claws 53 are provided on the right side of the drum 44.
There is a corresponding dial 4 for changing the day of the week.
An actuator 54 is formed on the inner surface of the drum 9 and engages with the pawl 53 to rotate the drum 44 one pitch at a time.

With the above configuration, you can easily display the month and Sunday, so
You can easily check the date of use, etc., and it can also be used as a desk calendar.

As mentioned above, in the present invention, the spool drive mechanism consists of a forward/reverse mechanism with a swing arm and a planetary gear inside the casing, and a reduction gear train arranged symmetrically around the pinion, and the rotating torque of the pinion is reduced. Since the planetary gear and one of the reduction gear trains are engaged with each other by the swinging of the arm following the movement of the gear, there are advantages that the number of parts is small and automatic forward/reverse control can be performed accurately.

In addition, the spool is removable, making it easy to replace the strip of paper.Moreover, the drive mechanism for feeding out the memo paper and the switch mechanism for turning it on and off are bulky, so they can be assembled in a compact form. As a result, the device can be provided as a compact device as a whole.
