Description

[Detailed description of the invention] This invention is a printing medium (printing medium) for a printer cover in a printer.
The present invention relates to a printer journal retrieval mechanism for retrieving printer journals (referred to as journals).

In a unit that houses journals and the like of a printer used as a terminal device, a cover is usually provided to cover the printer body in order to prevent dust from entering the journal portion.

Further, this cover is secured with screws to prevent it from vibrating due to external vibrations and damaging various parts within the housing.

However, with these conventional cover locking methods,
For example, just replacing the journal requires opening the cover covering the printer body, which is disadvantageous in that it requires more effort than necessary.

SUMMARY OF THE INVENTION The purpose of the present invention is to propose a journal retrieval mechanism that allows the journal to be easily removed in order to eliminate the above-mentioned drawbacks.

In order to achieve the above purpose, the present invention provides a journal cover for taking out the journal on the printer cover.
When the operator rotates the key, this action is used to release the latch from the stopper provided on the journal cover, and the journal cover can be locked without requiring a large rotational force when rotating the key. This makes it possible to solve the problem, and prevents it from being modified.

Hereinafter, the present invention will be explained based on a cross-sectional view of an embodiment of the present invention shown in FIGS. 1 and 2, and detailed views of essential parts thereof.

In the figure, 1 is a desk, 2 is a key manual device, 3 is a printer,
4 is a front inserter unit, 5 is a printer cover, 6 is a housing, 7 is a hinge, and 8 is a key receiving part.

The desk 1 is configured such that a key manual device 2 and a printer 3 are placed on different surfaces, and a recording paper insertion portion (not shown) for the printer 3 is located at a position that is easy for the operator to operate. .

The printer 3 has a casing 6 in which its control unit or power source is housed, and a frame in which these electric circuits are housed.The printer 3 has a housing 6 in which its control unit or power source is housed, and a frame in which these electric circuits are housed. The units are attached and the entire unit is covered with a printer cover 5.

Further, the printer cover 5 has a housing coupled to it by a hinge 7 so that it can be opened and closed.

The front inserter unit 4 is placed on this printer cover 5 and can be removed at the position indicated by the broken line in the figure. They are connected by gears, etc., and are configured so that paper sheets can be sucked in and ejected.

The printer unit has a supply reel 9 wrapped with recording paper.
A platen center 10 that pulls the recording paper on the supply reel 9 to the printing position, a printing unit 11 that prints on the recording paper drawn into the platen center 10, and a journal winding reel that winds up the printed recording paper. When the take-up reel 12 or the supply reel 9 is to be removed, the key is inserted into the key receiving part 8 of the orbta key and rotated to release the later-described locking part of the journal cover 13, and the front inserter unit is removed. 4 and journal cover 1
It is made removable by removing 3.

The locking mechanism of the journal cover 13 is shown in FIG.

Components corresponding to FIG. 1 are designated by the same numbers.

The operator inserts the key 80 into the key receiving part 8 and
0 rotates, a disk 81 provided at the bottom of the key receiving portion 8 rotates.

A cam 82 that locks the wire 14 is provided on the disc 81, and when the key 80 is rotated, the wire 14 is pulled in the direction of the arrow.

A tension adjuster 15 is provided on the wire 14, so that the wire 14 has a predetermined tension in advance.

When this wire 14 is pulled in the direction of the arrow, the lock lever 1
6 rotates in the vertical direction around a shaft 18 because the wire 14 is locked in the hole 17 of the lock lever 16.

The lock lever 16 also has an arm 19, and its vertical rotation presses the arm 21 of the lock lever 2o to rotate the lock lever 20 about a shaft 22.

The lock lever 20 has a latch 23 at the other end, and is normally rotated counterclockwise by a spring 25 fixed to a fixture 24 and engaged with the tip of a stop 26 extending from the journal cover 13. It's like that.

As mentioned above, the arm 19 of the lock lever 16 is connected to the lock lever 2.
When the arm 21 of 0 is pressed and rotated about the shaft 22, the latch 23 is released from the stopper 26, and the journal cover 13 can be removed.

In addition, at this time, as a configuration of the lock lever 20, the length from the shaft 22 to the engaging portion 9 of the arm 21 with the arm 19 is as follows.
By adopting a structure that is longer than the length from the shaft 22 to the part where the stopper 26 and the latch 23 engage, the lever action is utilized and even if the rotational force applied to the key 80 is small, locking can be performed. It will be canceled.

Furthermore, if you want to lock the journal cover 13 again, use the key 8.
By simply pushing in the journal cover 13 from the top surface of the printer cover 5 with 0 removed, the lock lever 20 rotates, the stopper 26 slides on the slope of the latch 23 and reaches the engagement part, completing the locking.

As described above, the present invention further includes a cover for taking out the journal on the printer cover, and by providing a locking mechanism on this cover, it is possible to prevent tampering with the journal, and the journal cover can be removed without opening the printer cover of the printer body. Opening allows you to take out the journal more easily than before.
