Abstract

PROBLEM TO BE SOLVED: To perform smooth mounting of a belt-like object containing device on a device body through prevention of the occurrence of a slack of a belt-like substance. SOLUTION: In such a state that a ribbon cassette 100 is separated away from an issuing machine body, a spool 111 is energized to the back side through the force of a spring member 107, and the groove 115a of a collar part 115 is engaged with the chevron-form protrusion 106 of a back case 101b to lock rotation of the spool 111. Thereby, even when vibration is exerted during mounting, a slack of a ribbon (the belt-like substance) 110 is prevented from occurring, and mounting on the issuing machine body is facilitated. When the ribbon cassette 100 is mounted on the issuing machine body, a drive shaft 50 is fitted in a fit-in hole 117a, and the drive shaft 50 presses the spool 111 toward the surface side against the press force of a spring part 107. The groove 115a of the collar part 115 is separated from the chevron protrusion 106 of the back case 101b, and the spool 111 is brought into a turningly movable state through the drive force of the drive shaft 50.

In this conventional card issuing device, a ribbon cassette is used for printing on a card-shaped medium.

The ribbon accommodated in the ribbon cassette is taken out from the supply side spool and wound around the winding side spool via the stay.

[0005]

However, in the conventional ribbon cassette, the supply-side roll and the winding-side roll are
Since the structure is such that it is pressed in the axial direction by a leaf spring, if vibration or the like is applied to the ribbon cassette when it is mounted on the apparatus main body, the ribbon will slacken and jump out to the transport path for the card-shaped medium, which makes mounting difficult. Further, even if the card can be mounted, there is a problem that the ribbon protruding in the transport path hinders the transport of the card-shaped medium and causes a transport abnormality.

Therefore, the present invention has been made in view of the above, and an object of the present invention is to provide a band-shaped body accommodating device capable of preventing loosening of the band-shaped body and enabling smooth mounting on the apparatus body. It is a thing.

[0007]

In order to achieve the above-mentioned object, the present invention provides a container and a belt-shaped body accommodating device which is detachable from a main body of a device for driving and driving the belt-shaped body. The pair of supported winding shafts, the strip-shaped body wound around the pair of winding shafts, the rotation of the pair of winding shafts in a state of being separated from the device body, and the device body. A slack prevention mechanism for releasing the lock based on a mounting operation on the.

According to the present invention having the above-mentioned structure, the rotation of the pair of winding shafts is locked by the slack preventing mechanism when the device is detached from the apparatus main body. Therefore, it becomes possible to prevent the band-shaped body from loosening even when vibration is applied during mounting, and the mounting on the apparatus main body becomes easy. When mounted on the device body, the lock is released by the loosening prevention mechanism, and the belt-shaped body can be driven to travel.

And a ribbon slack prevention mechanism that prevents the ribbon 110 from slacking in the detached state.

First, the mounting and holding mechanism will be described.

Two lock rods 5 are provided on the issuing machine main body 2A side.
1 is provided. The lock rod 51 has a groove 51a formed on the tip side thereof. When the operator holds the handle 103, inserts the lock bar 51 into the guide cylinder 108, and pushes it into the mounting position, the locking claw 10 is inserted into the groove 51 a of the lock bar 51.
9 is locked and the mounted state is maintained.

Yes, it is configured as follows.

Back side shaft end 117 of supply side spool 111
Are supported by the bearing holes 104, and the front shaft end portion 118 is
Are supported by the bearing portion 105. As a result, the supply side spool 111 is rotatably supported in the case 101, and the back side shaft end 117 is provided in the case 1.
It is supported so that it can appear and disappear from 01. That is, spool 1
11 is supported so as to be movable in the axial direction between a lock position where rotation is locked and a release position where lock is released.

In the detached state from the main body 2A of the issuing machine, the supply side spool 111 is in the lock position biased to the back side by the spring member 107. At this lock position, the groove 115a of the saliva portion 115 and the mountain-shaped projection 106 of the back side case 101b are engaged with each other to lock the rotation of the supply side spool 111.

On the issuer body 2A side, the supply side spool 1
Drive shafts 50, 50 are rotatably provided at positions facing 11 and the winding-side spool 113.

When the operator holds the handle 103 and mounts the ribbon cassette 100 on the issuing machine main body 2A as shown in FIG. 8, the drive shaft 50 is fitted into the fitting hole 117 as shown in FIG.
The drive shaft 50 pushes the supply side spool 111 to the front side against the pressing force of the spring portion 107. Then, the groove 115a of the saliva portion 115 is detached from the mountain-shaped projection 106 of the back case 101b, and the supply side spool 111 becomes rotatable by the driving force of the drive shaft 50.

As described above, the present ribbon cassette 1
00 is a pair of spools 111, 112 due to the ribbon slack prevention mechanism in the detached state from the issuing machine main body 2A.
Since the rotation of the ribbon 110 is locked, the ribbon 110 can be prevented from being loosened even when vibration is applied during the mounting, and the ribbon 110 can be easily mounted on the issuing machine main body 2A.

Further, by only inserting the ribbon cassette 100 into the main body 2A of the issuing machine, the groove 5 of the lock rod 51 can be removed.
Since the locking claw 109 is locked to 1a and the lock is automatically released by the ribbon slack preventing mechanism to enable the traveling drive, the mounting operation can be easily performed.

Since the spring portion 107 is integrally formed when the front case 101a is formed, a separate spring member is not required, so the number of parts is reduced and the ribbon cassette 1
The assembly work of 00 becomes easy.

Further, since the height positions of both spools 111 and 113 are made different, the width dimension can be made smaller, so that a plurality of ribbon cassettes 100 can be arranged along the conveying path as in the present card issuing machine 2. When they are arranged side by side, the size in the transport path direction can be made small.

The present invention is not limited to the above-mentioned embodiments, and various embodiments are possible.

For example, although the ribbon cassette has been described in the above embodiment, the present invention can be similarly applied to a tape cassette for recording.

In the above embodiment, a plurality of engaging portions (grooves) are provided on the spool side, and one engaging portion (mountain-shaped protrusion) is provided on the case side. A locking portion may be provided and a plurality of engaging portions may be provided on the case side.

In the above embodiment, the spring portion 10 is used.
Although 7 is formed integrally with the front case 101a, the spring member may be manufactured separately and attached to the front case 101a.

[0065]

According to the present invention described in detail above, since the rotation of the pair of winding shafts is locked by the slack preventing mechanism in the detached state from the main body of the apparatus, even if vibration is applied at the time of mounting, the belt-like shape is formed. It is possible to prevent the body from slackening, and the device can be easily attached to the body.

Further, since the lock is released by the loosening prevention mechanism based on the mounting operation to the main body of the apparatus and the belt-shaped body can be driven to travel, the mounting work becomes easy.
