Description

[Detailed Description of the Invention] The present invention relates to an information tape holding device for a paper tape reader or punching machine.

A tape feeding mechanism is essential in a tape device that serves as an input/output device for a computer.

The tape holding device, which is buttoned on the feeding mechanism, opens and closes when attaching and detaching the tape, but this opening and closing operation is troublesome, and there is a risk that the tape may be damaged or cut when attaching or detaching the tape.

The purpose of this study is to provide an information tape holding device that is simple in structure and easy to assemble and adjust, making it easy to attach and detach the tape and eliminate problems such as damage to the tape. .

Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

Legs 4 of a presser plate 3 are inserted into holes 5 of a top plate 2 which is a running surface of the information tape 1.

This leg portion 4 is located on one side of the presser plate 3, has an abbreviated shape with one side of the presser plate 3 bent downward, and has an included angle of about 45 mm with the flat surface of the presser plate 3. It is folded so that it is at the front and back.

A hole 6 is formed on the opposite side of the top plate 2, sandwiching the information tape 1 between the hole 5 (into which the legs 4 are inserted), and the claw 7a of the lock plate 7 projects onto the top plate 2 from this hole 6. has been done.

This lock plate 7 is rotatably attached to a bracket 8 provided on the lower surface of the top plate 2 with a pin 9.

When the lowermost end 7' of the lock plate 7 comes into contact with the lower surface of the top plate 2, the uppermost end T of the lock plate 7 sinks into the hole 6 and is positioned at the same level or lower than the upper surface of the top plate 2. It has become.

The side edge of the holding plate 3 and the claw 7 of the locking plate 7
It is designed to engage with a.

The side end 3' is bent so as to rise slightly, and is caught by the claw 7a of the rotatable lock plate 7.

The base end of the leg 4 and the bracket 8 and the base end of the leg 4 and the lock plate 7 are connected by springs 10 and 11, respectively.

The spring 10 always urges the presser plate 3 in the direction of rising (opening).

The spring 11 has both ends attached to the leg portion 4 and the lock plate 7 with screws 12.12, and functions to cause the claw 7a of the lock plate 7 to protrude above the top plate 2 when the presser plate 3 is folded down.

That is, when the presser plate 3 is folded down, the spring 11 is pulled so as to rotate the lock plate 7 in the rising direction as the leg portion 4 rotates.

Next, the operation of the present invention will be explained. To open the presser plate 3 (to raise it up) in order to attach or detach the information tape 1, the claw 7g of the lock plate 7 is pressed.

Then, the lock plate 7 rotates clockwise in FIG.
When the engagement between the claw 7a and the side end 3' of the holding plate 3 is released, the holding plate 3 is rotated counterclockwise in FIG. 2 by the tensile force of the spring 10. It means opening (standing up).

At this time, the spring 11 is completely compressed and the lock plate 7
The lock plate 7 functions as a rod that rotates the lock plate 7 clockwise in the figure, thereby causing the lock plate 7 to sink below the surface of the top plate 2.

When the lock plate 7 sinks below the surface of the trap plate 2, there is no protrusion on the surface of the top plate 2, so that the information tape 1 can be moved by sliding on the surface of the top plate 2.

Next, when closing the open presser plate 3, close the presser plate 3.
The side end 3' is pushed downward and rotated clockwise in the figure using the bending point between the leg portion 4 and the presser plate 3 as a fulcrum against the tensile force of the spring 10.

The spring 11 gradually expands as the holding plate 3 rotates, and rotates the lock plate T counterclockwise in the figure.

Then, the claws 7a of the lock plate 7 protrude from the holes 6 to the surface of the top plate 2 and engage with the side edges of the presser plate 3, so that the presser plate 3 and the lock plate 7 are both fixed.

As explained above, according to the present invention, if the lock plate is simply pushed down with a finger, the holding plate opens due to the force of the spring, and the lock plate or another spring sinks from the surface of the top plate, allowing the information tape to be To take out or put on the information tape, all you have to do is slide it on the top plate surface, and the information tape can be put on and taken off quickly and easily.

In addition, holes for inserting the legs of the holding plate and holes for protruding the lock plate are drilled on both sides of the area where the information tape runs on the top plate, and the legs, lock plate, and legs are inserted on the back side of the top plate. Since the brackets of the lock plate and the lock plate are simply connected by springs, assembly and disassembly are extremely easy, and the structure is also simplified.

Therefore, it is also advantageous in terms of cost.

Furthermore, the degree of opening and closing of the presser plate can be easily adjusted by simply changing the tension of the spring.
