Abstract: PURPOSE: To obtain a compact type pump system, which is easily handled and installed and capable of operating safely with a simplified mechanism, by attaching a vacuum pump and a rotary-driving reduction gear onto a pump casing.  
     CONSTITUTION: A common attaching frame 22 having a length equal to diameter of a side wall 16 is fixed onto the side wall 16 of a pump casing 4, and a vacuum pump 30 and a reduction gear 21 are attached onto this attaching frame 22 in a free-to-put-on-and-off arrangement.

Title: Endless belt and image forming device therewith
Inventor: MAEKAWA ICHIRO
IPC: G03G21/00
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent a transfer belt from moving biasedly with a simple structure and at low cost. SOLUTION: This device is provided with a driving roller 115 and driven rollers 116, 117, 118 with a transfer belt 114 tensed tightly around them to rotate the transfer belt 114 in the arrowhead direction at a speed of V2 by means of the friction between the outer periphery surface of the driving roller 115 and the inner periphery surface of the transfer belt 114. Both end parts on the inner periphery surface of the transfer belt 114 are formed with surfaces (a), (c) having a high coefficient of friction, and a surface (b) having a low coefficient of friction is formed at the central part. For example, if the transfer belt 114 biasedly moves, being dislocated in the plus (+) direction, the contact area of the outer periphery surface of the driving roller 115 with the surface (c) having a high coefficient of friction becomes larger that with the surface (a) having a high coefficient of friction; thus a force restoring the transfer belt 114 to the minus (-) side acts upon it.
