Description

[Detailed description of the invention] This invention relates to a lamp house for a heat-sensitive stencil printing device that can make and print heat-sensitive stencil paper.The purpose of the invention is to make the lamp house small and to obtain uniform illumination. I'm trying to make it possible.

As shown in Japanese Utility Model Publication No. 57-15814, in the lamp house of conventional thermal stencil printing equipment, the flash bulb was attached to the top and the housing had to be removed to replace the flash bulb, so the lamp house could be lowered. The drawback was that it was troublesome to replace the Zumata flash valve.

The present invention eliminates the drawbacks of the conventional lamp by allowing the flash bulb to be attached and removed together with the socket on both side walls of the casing (lamp house).

Next, an embodiment of the present invention shown in the accompanying drawings will be described in detail. 1 is a base on which an elastic plate 2 such as a flat rectangular sponge is fixed, and both side walls 1a
A guide groove consisting of a vertical groove 1b and a horizontal groove 1c facing outward from the middle on the inner surface of one end, and a diagonal groove facing inward and obliquely upward facing the same vertical grooves 1b, lateral grooves 1c, and lateral grooves 1c on the inner surface of the other end. A guide groove of 1d is formed. 3 is a lamp house with a transparent press plate 4 on the bottom surface
is fixed thereto, and a paper frame support member 5 for fixing the heat-sensitive stencil paper is attached to its outer periphery. At the lower four corners of the lamp house 3 are shaft pins 6 made of conductive material.
is pivoted and protrudes, its tip is fitted into the vertical groove 1b, a square lever 7 is fixed in the middle of the protrusion, a pin 8 is provided at the inner tip, and a pin 9 is provided horizontally on the outer tip. , a pin 9 is fitted into the horizontal groove 1c. A press cover 10 is attached to the upper part of the lamp house 3, and legs 10a projecting downward from the four corners thereof are placed on pins 8, respectively. The inside of both side walls 1a of the base 1 is hollow, and a conductive movable leaf spring 11 is disposed on one side, and conductive movable leaf springs 12 and 13, which are divided into two, are disposed on the other side. It protrudes into the vertical groove 1b, and the tip of an electrically conductive shaft pin 6 is placed thereon. Each movable leaf spring 11, 12, 13 is supported by a spring 14, and each movable leaf spring 11, 12, 13
Bent contact plates 15a and 16a are positioned below the outer ends of the plate springs 15 and 16 to face each other, and a battery 17 is fitted in series to one of the plate springs 15. Socket insertion openings 3a are formed in both side walls of the lamp house 3 and are large enough to allow the flash bulb 18 to enter and exit, and the socket 19 is inserted into the socket 19 by holding the grip 19a in one's hand. The shaft pin 6 placed on the movable leaf springs 12 and 13 is connected to one socket 19 by the current-carrying plate 20.
The other socket 19 is connected to a current-carrying plate 20 via a current-carrying plate 21. The switches S ₁ , S ₂ , S ₃ , S ₄ constituted by movable leaf springs 11, 12, 13 and leaf springs 15, 16, the flash valve 18, and the battery 17 are shown in FIGS. 7 and 8. are connected in series. Next, the effect will be explained.

When the press cover 10 with the lamp house 3 attached is lifted upward, the pin 9 is inserted into the vertical groove 1b as shown in FIG.
The lamp house 3 can be removed from the base 1 by lifting it further upwards. In this way, the lamp house 3 is removed, the heat-sensitive stencil paper 22 is fixed to the base paper frame support member 5 on the lower surface, the original 23 is placed on the elastic plate 2 of the base 1, and the pin 9 of the lamp house 3 and the shaft are fixed. Pressing cover 1 with pin 6 inserted into vertical groove 1b and lamp house 3 attached
Due to its own weight of 0, the pin 9 enters the horizontal groove 1c as shown in FIGS. 10 and 13. In this state, press cover 10
When the lever 7 is pushed downward, the lever 7 is moved to the pin 9 as shown in Fig. 11.
The pressing plate 4 is rotated as shown by the arrow about the fulcrum, and the pressing plate 4 is pushed downward by the shaft pin 6. Since the shaft pin 6 is closer to the pin 9, which is the fulcrum, than the pin 8, which is the point of action, it is pushed with a force that is sufficiently larger than the force that pushes the pressing cover 7 due to the lever principle. When the pressing plate 4 presses the document 23 and reaches the final position as shown in FIG.
1, 12, and 13 are pressed against the leaf springs 15 and 16 against the elasticity of the spring 14, and the switches S ₁ , S ₂ , S ₃ , and S ₄ shown in FIGS. 7 and 8 are closed. The machine is energized, lights up, and platemaking begins.

When printing next time, as described above, lift the press cover 10 covering the lamp house 3 upward and remove it, remove the plate-made heat-sensitive stencil paper 22 from the base paper frame support member 5 on the bottom surface of the lamp house 3, and apply ink. Then, attach it to the base paper frame support member 5 again, and then attach it to the base 1.
A printing paper 24 is placed on the elastic plate 2, and the press cover 10 with the lamp house 3 covered thereon is mounted on the base 1 and pressed to perform printing.

When the lamp house 3 is rotated upward around the shaft pin 6 on the side with the diagonal groove 1d as shown in Fig. 4 without removing it from the base 1, the pin 9 fits into the diagonal groove 1d and rotates vertically upward. Since the heat-sensitive stencil paper 22 can be rotated in this state, the heat-sensitive stencil paper 22 may be attached or detached.

In addition, the lamp house 3 is lifted upward and removed as described above, and the heat-sensitive stencil paper 2 is placed on the underside of the lamp house 3.
It is also possible to attach the stamp 2 with ink applied to it and press it onto various objects as a stamp to print.

According to the present invention, a socket insertion opening large enough to allow the flush valve to enter and exit is provided on both side walls of the housing, and a socket having a gripping portion and attached with the flush valve is attached to this socket insertion opening, so that the flash valve can be inserted into the socket. are arranged horizontally on both sides, allowing the housing to be lowered, and the flush valve can be attached and removed by grasping the grip along with the socket without removing the housing, making it easy to replace the flush valve in an extremely short time. can be done.

The present invention can also be applied to a lamp house of a thermal stencil printing apparatus in which one end of a pressing plate having a lamp house is pivotally connected to a base.
