[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer which is mounted on a vehicle or the like and records the operating state of the vehicle, and more particularly to a mounting device of a vehicle-mounted printer for mounting the printer on a vehicle.

[0002]

2. Description of the Related Art In general, an in-vehicle printer is often used mainly for recording the operation status of a commercial vehicle, for example, a taxi, and therefore, it has been developed on the premise that the printer is mounted inside a passenger car. . Conventionally, such an in-vehicle printer uses an anti-vibration rubber 101 as shown in FIG. 9, which is a detailed view of a part D in FIG. The anti-vibration rubber 101 is interposed between the front case boss 103 and the back case 105 of the printer, and
And is fixed to the printer body by tapping screws 109. Then, the printer main body is fixed to a predetermined portion of the vehicle using a mounting hole formed in a mounting flange 110 provided at the bottom of the printer main body.

[0003]

However, when such an in-vehicle printer is mounted on a construction vehicle having a poor use environment, the following problems occur.

(1) The forced frequency differs depending on the use environment of the user, and the hardness of the vibration isolating rubber 101 must be changed for each user. At that time, a complicated operation of removing the tapping screw 109 is required. Becomes

(2) The anti-vibration rubber 101 is not so high in the anti-vibration function used in a taxi or the like. Two models with specifications are required, and parts management becomes complicated. (3) Peripheral dust and water enter through the paper exit on the front of the printer, clogging gears that constitute the internal mechanism,
Or, if a sensing abnormality of the photo sensor occurs,
The function as a printer is impaired.

For the problem (3), for example, FIG.
As shown in FIG.
3 and the upper opening 115 of the dustproof film 113 is covered with the dustproof cover 117, but in this case, the following problem occurs.

[0007] Rain water enters inside the printer due to blowing from below, and dust and water enter through gaps between the roll paper cover and the printer body and various switch gaps.

The dustproof film 113 loses its elasticity due to a change in temperature and a change with time, and a large gap is formed in the opening 115. As a result, dust enters the inside of the printer by blowing from below. In addition, the dust-proof film 11 is changed by the temperature change.
In the case where the elasticity of the sheet 3 becomes strong, the gap of the opening 115 is lost and the sheet cannot be discharged.

It is conceivable to change the design of the printer main body with respect to the above-described measures against vibration, dust, and water. However, in this case, the printer is redeveloped, resulting in a significant increase in cost.

[0010] Therefore, the present invention aims at fully utilizing the functions of dust prevention, waterproofing and vibration proofing by using a conventional in-vehicle printer as it is.

[0011]

The printer case 1 has a bottom surface 15 facing a printer mounting portion (not shown) on the vehicle side, and front, rear, left and right peripheral side surfaces 17, and a front glass 19 serving as an opening / closing plate is provided on an upper surface opposite to the bottom surface 15. An opening 21 closed by the opening 21 is formed. At three places on the bottom surface 15 of the printer case 1, the mounting holes 9 and the mounting holes 11, 13 of the printer 3 are provided.
Mounting portions 23, 25 and 27 are provided. As shown in detail in FIG. 5, the mounting portions 23, 25, and 27 have protrusions 23a,
25a, 27a are formed and recesses 23b, 2
5b and 27b are formed.

Mounting holes 23c, 25c, 27c are formed in the protrusions 23a, 25a, 27a.
A fixing member 29 for fixing the printer case 1 to a printer mounting portion (not shown) on the vehicle side is attached to the printer 3 using c, 25c, and 27c. Fixture 29
Is composed of a rubber portion 29a as an elastic body and screw portions 29b and 29c embedded at both ends of the rubber portion 29a. One of the screw portions 29b constitutes a printer-side fixing portion which is inserted into the mounting holes 9, 11, 13 on the printer 3 side and is fastened by the nut 31, and the other screw portion 29c serves as the printer mounting portion. The vehicle-side fixing portion is inserted into a mounting hole formed in the mounting plate and fastened with a nut from the back side of the mounting plate.

A hinge attachment portion 33 is formed at the end of the peripheral side surface 17 at the upper end in FIG. 1 of the printer case 1 on the opening 21 side, and the upper end of the front glass 19 is attached to the hinge attachment portion 33. A hinge 35 that is rotatably attached to the printer case 1 is mounted. The hinge 35 constitutes a rotation support portion that can be opened and closed by rotation about the opening 21 with one side of the front glass 19 as a fulcrum.

A knob 37 which is gripped when opening and closing the front glass 19 is attached to the lower side of the front glass 19 in FIG. The knob 37 has a mounting shaft 39 rotatably penetrating the front glass 19 and protrudes toward the printer case 1. On the other hand, a concave portion 41 is formed in the peripheral side surface 17 between the mounting portions 25 and 27 of the printer case 1, and a flat portion 43 is formed at an end of the peripheral side surface 17 on the opening 21 side in the concave portion 41. I have. 6 and 7, a rectangular opening 43a is formed in the flat portion 43. When the front glass 19 is closed, the mounting shaft 39 of the knob 37 is formed in the opening 43a. It becomes a configuration to enter.

The front glass 1 at a position matching the opening 43a
A mounting plate 39 is rotatably inserted and supported on the back surface of the fixing plate 45 so as to be in contact with the front glass 19, and a support plate 47 which is rotatably supported at the tip of the mounting shaft 39 and is bent in a crank shape. Are fixed by screws 49 and nuts 51. The mounting shaft 3 is provided between the fixing plate 45 and the support plate 47.
A claw 53 and a coil spring 55 which are screw-coupled to 9 are interposed. When the claws 53 close the front glass 19,
The front glass 1 is locked to the flat portion 43 on the printer case 1 side.
The pressing mechanism 9 restricts the opening of the printer 9 and presses the flat portion 43 on the side of the printer case 1 against the front glass 19. On the other hand, the coil spring 55 presses the claw 53 on the side opposite to the fixing plate 45. This pressing operation prevents the claw 53 from freely rotating with respect to the screw portion of the mounting shaft 39.

When the claw 53 is at a position A indicated by a two-dot chain line in FIG. 7 which is a left side view of FIG. 6, the claw 53 is in the opening 43a and is not locked to the flat portion 43 on the printer case 1 side. At this time, the claw 53 is fixed to the fixed plate 4 by the coil spring 55.
5 and is pressed against the threaded portion of the mounting shaft 39 to prevent movement to another position. By pulling the knob 37 in this state, the front glass 19 can be opened.

In this state, when the knob 37 is rotated to the right by about 90 degrees in FIG. 7, the claw 53 is also rotated in the same direction and moves to the position B. The rotation of the claw 53 further rightward from the B position is regulated by a stopper (not shown). When the knob 37 is further turned to the right, the claw 53 screwed to each other moves in the direction C against the mounting shaft 39 against the coil spring 55, and the flat portion 4
3 is pressed. As a result, the rightward rotation of the knob 37 becomes impossible, and the front glass 19 is closed.

When the knob 37 is rotated to the left from the closed state of the front glass 19, that is, the state where the claw 53 is at the position B, the mounting shaft 39 is rotated with respect to the claw 53 and the flat portion 43 of the claw 53 is rotated. The pressure contact with is released. When the frictional force due to this pressure contact is eliminated, the claw 53 rotates together with the mounting shaft 39 and moves to the position A. The rotation of the claw 53 further leftward from the position A is regulated by a stopper (not shown). When the knob 37 is further rotated leftward from this state, the claws 53 screwed to each other are attached to the mounting shaft 39.
6 moves rightward in FIG. 6 and contacts the support plate 47. In this state, the knob 37 cannot be turned to the left, and the front glass 19 can be opened.

A groove 57 is formed over the entire periphery of the end of the printer case 1 on the side of the opening 21. In this groove 57, a sealed glass 19 is brought into close contact with a seal to exert a sealing function. A packing 59 is inserted as a material. The packing 59 is located inside the respective mounting portions of the hinge 35 and the knob 37 described above. Also, as shown in FIG. 4, an extraction hole 63 for taking out the lead wire 61 shown in FIG.

When the printer 3 is mounted on a poorly used environment, for example, a construction vehicle, using the mounting device for a vehicle-mounted printer thus configured, the rubber portion 29 of the fixture 29 is used.
a absorbs vibration during operation of the vehicle, and the front glass 19 covers the printer case 1 in a hermetically sealed state via a packing 59.
Provided inside the hinge 35 and the knob 37, the provision of these components does not cause deterioration of the sealing performance, and prevents dust and water from entering the printer case 1 and, as a result, the operation of the printer 3 Defects are prevented. Further, since the fixing device 29 fixes the printer 3 on the bottom surface of the printer case 1 in close contact with the screw portion 29b, a clearance between the printer 3 and the printer case 1 becomes unnecessary, and the size of the printer case 1 is reduced. And cost reduction is achieved. The fixing device 29, the printer case 1 and the front glass 19 can be set as optional parts for a construction vehicle or the like. Therefore, when the printer 3 is mounted on the vehicle, these may be mounted as necessary. With regard to the above, the complicated operation of removing the tapping screw when replacing the vibration isolating member as in the related art becomes unnecessary, and the mounting operation becomes easy, and the fixing tool 29 serving as the vibration isolating member is an optional component. Therefore, it is sufficient to prepare a plurality of types of the fixing tool 29 itself according to the use environment, and it is not necessary to prepare a plurality of types of printers, which facilitates parts management and is advantageous in cost. Further, since the printer 3 of the conventional specification can be used as it is, a significant increase in cost as in the case of changing the design of the printer 3 itself can be prevented.

The paper printed and printed out by the printer 3 is discharged to a discharge paper storage space 4 between the printer 3 and the printer case 1. The ejected paper is
The knob 37 is turned to release the engagement of the claw 53 with the flat portion 43, and the front glass 19 is turned upward with the hinge 35 as a fulcrum and is taken out in an open state.

In the above-described embodiment, the vibration proof, dust proof, and water proof functions are exhibited by using the fixing portion 29, the printer case 1, the front glass 19, and the like. However, the present invention is not limited to this. Only the anti-vibration function is exhibited by using only the fixture 29, and the printer case 1 and the front glass 19
It is also possible to adopt a configuration in which only the dustproof and waterproof functions are exhibited by using only the above.

[0027]

As described above, according to the present invention, the press-contact mechanism provided on the knob presses the printer case-side portion against the back side of the opening / closing plate to improve the degree of sealing by the sealing material. Since the material is provided inside the rotation support portion and the knob of the opening and closing plate, the provision of these materials does not cause deterioration of the sealing property, and ensures that dust and water enter from the paper outlet of the printer. Can be prevented. Further, an elastic body provided on a fixing device for fixing the printer case to the vehicle side is interposed between the printer case and the mounting portion on the vehicle side to absorb the vibration on the vehicle side, and the fixing device includes: Since the printer is fixed in close contact with the bottom surface of the printer case by the printer-side fixing portion, no clearance is required between the printer and the printer case, and the size and cost of the printer case can be reduced. The fixing device, the opening / closing plate, and the printer case can be set as separate components from the printer, and the conventional printer can be used as it is, so that a significant increase in cost, such as when the design of the printer itself is changed, is prevented. .
