Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to a transfer device for selectively transferring a donor layer of a transfer tape to a xerographic image.

[0002]

2. Description of the Related Art Conventionally, a transfer device shown in FIG. 5 has been known (JP-A-6-210830). In this transfer device, a transfer tape 23 is stretched so as to pass through the lower surface of the front end of the transfer head C located at the lower end. A heat-generating head 40 is provided at the tip of the transfer head C, and when used, the transfer tape 2 is heated by the heat-generating head 40.
3 is a xerographic image forming surface (transferred substrate 80)
Press up. Then, when the transfer device is moved in this state, the transfer tape 23 is sequentially fed by the frictional force,
The color layers (donor layers) of the transfer tape 23 heated and pressed by the heating head 40 are sequentially transferred onto the xerographic image. In this way, the transfer is selectively performed on a predetermined xerographic image.

[0003]

As described above, the transfer device is used by scanning while the heating head 40 is in contact with the transferred substrate 80. It is necessary to scan while the entire surface of the transfer tape 23 is in contact with the transferred substrate 80. In other words, the heating head 4
It is necessary to perform scanning with the lower end surface of 0 and the transferred substrate 80 kept parallel to each other. Therefore, when the user actually performs the transfer, it is necessary to scan the transferred substrate 80 while keeping the apparatus main body vertically.

Therefore, as shown in FIG. 6, when the main body of the apparatus tilts to the left or right with respect to the scanning direction (transfer direction) during scanning, it is located between the heating head 40 and the transfer substrate 80. In some cases, a void is generated, the intended selective transfer is not performed, and the transfer cannot be performed appropriately. Further, if the transfer is performed with the transfer head tilted, the transfer head may be damaged by the transfer head. It should be noted that such a transfer failure does not occur if the user always scans the apparatus main body while keeping the apparatus main body vertically, but it is practically difficult to always perform scanning in such a state. there were.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a transfer device capable of preferably performing transfer even when the main body of the device is slightly inclined with respect to the transfer substrate. To provide.

[0006]

Therefore, a transfer device according to the present invention accommodates a transfer tape, and a device main body provided with a tape accommodating portion for accommodating the transfer tape after attachment, and a device main body protruding from the device main body. A transfer head that heats up to a predetermined temperature, presses the transfer tape sent from the tape housing portion to a xerographic image, and a holding body that holds the heating element. A pair of support members are provided which are fixed to the apparatus main body and are arranged on both sides of the holding body in the transfer direction and slidably support the holding body. Then, the holding body is configured such that the side surfaces contacting the pair of support members are rounded so that the pair of support members can be tilted along the circumference of the holding body.

A feature of the present invention is that the corners of the holder are rounded so that the pair of supporting members can tilt around the holder around the transfer direction.

Further, the holding body has supporting projections protruding on both sides in the transfer direction, and each supporting member has a guide groove for receiving the supporting projection therein, and the supporting projections of the holding body are guide grooves. By displacing the inside, the holding body can be slidably supported by the pair of support members.

[0009]

When the user grips the device body and scans the device body, if the device body tilts to the left or right with respect to the transfer direction, the supporting member fixed to the device body also tilts. In this case, if substantially the entire side surface of the holder is in contact with the support member, the holder sandwiched on both sides by the support member is also tilted, resulting in the state shown in FIG. Therefore, as in the present invention, by making the side surface of the holding body round, it becomes a mechanism capable of relatively tilting the periphery of the holding body while both supporting members hold the holding body. As a result, even when the apparatus main body is tilted to the left or right with respect to the transfer direction, the lower end surface of the heating element can always be maintained in parallel with the transfer surface.

Therefore, as shown in FIG. 4, when the apparatus body 1 is tilted in the direction of arrow b, the support members 51 and 52 are tilted in the direction of arrow b around the head holder 41, but the head holder 41 is While maintaining the pressed state, the transfer tape 23 can be pressed against the transferred substrate 80 by the entire lower end surface of the heat generating head 40. The same applies when the apparatus body 1 is tilted in the direction opposite to the arrow b, and the support members 51 and 52 tilt in the direction opposite to the arrow b around the head holder 41, but the head holder 41 is in this pressed state. To maintain. As a result, even when the apparatus main body 1 is tilted to the left or right in the transfer direction, the lower end surface of the heat generating head 40 always presses the transfer target substrate 80 on its entire surface, so that the transfer is always performed properly. be able to.

In the head holder 41 described above, the side surface 47 facing the support members 51 and 52 is illustrated as being curved in a circular arc shape. The shape may be such that the side surface 47 of the head holder 41 is rounded so that the members 51 and 52 can tilt around the head holder 41.

Further, in the above structure, the support members 51,
Although the guide grooves 42 and 45 are provided in 52 and the support protrusions 43 and 44 are provided in the head holder 41, the guide groove is provided in the head holder 41 and the support member 51, It is also possible to adopt a configuration in which a support protrusion is provided on 52.

[0023]

As described above, in the transfer device according to the present invention, the holder for holding the heating element is supported by the pair of support members from both sides, and the side surface of the holder is rounded. Therefore, the pair of support members can be tilted along the outer periphery of the holding body. Therefore, even if the main body of the apparatus is tilted with respect to the transfer substrate, the heating element and the transfer substrate are maintained in parallel, so that stable transfer is possible.

Therefore, in the transfer apparatus of the type in which the user holds and moves (scans) the apparatus body in this way, conventionally, it is necessary to pay close attention so that the apparatus body is perpendicular to the transfer substrate. However, according to the transfer device of the present invention, the transfer work becomes extremely easy, and the transfer work can be performed efficiently. Further, since the surface to be transferred is not damaged, waste due to failure can be reduced, and stable and suitable transfer can be performed.
