摘要:
A belt unit including an endless belt, a first roller, a second roller, and a guiding member is provided. The guiding member includes a groove, in which a guided section of the endless belt is set, and the groove includes a first face and a second face. The first face is formed to have a first parting line extending in a direction to intersect with a central axis. The first face includes a first part in a frontward range and a second part in a rearward range with respect to the first parting line along a rotating direction of the guiding member. The first face has a first gap between the first part and the second part to form the first part in a position closer to the second face with respect to the second part.

An image forming apparatus includes a support frame having a first abutment portion, and a belt unit detachably attachable to the support frame and having a first abutted portion configured to be in contact with the first abutment portion. One of the support frame and the belt unit has a pressing portion, and remaining one of the support frame and the belt unit has a pressed portion pressed by the pressing portion so as to increase a contacting surface pressure between the first abutment portion and the first abutted portion. The pressing portion has a first contacting portion in contact with the pressed portion, and the pressed portion has a second contacting portion in contact with the first contacting portion. The first contacting portion and the second contacting portion are made from an electrically conductive material.

A spacer configured to minimize movement of a transfer unit (for example, a belt unit) is described. An apparatus may include a main body and a transfer unit disposed in the main body. The spacer may include various contact portions that contact a portion of the transfer unit and a portion of the main body to minimize relative movement of the transfer unit.

Disclosed herewith is a semiconductor data processing device that realizes low power consumption at the standby time and at the operation time, as well as speeds up the interfacing operation. The semiconductor data processing device can connect a non-volatile storage device to a general-purpose bus of a host system. The data processing device enters the active or standby state in response to the state of the general-purpose bus. In the standby state, the data processing device stops the internal clock signal and applies a substrate bias voltage to each object so as to suppress the potential sub-threshold leak current therefrom. This bias voltage is also applied to the central processing unit and the rewritable non-volatile memory for storing a control program to be executed by the central processing unit. The central processing unit processes data in units of n bits or below when the interface controller and the data transfer controller input/output parallel data in units of 2n bits.

A calibration device 21 according to the present invention is a member used for white calibration of an optical characteristic measuring apparatus 1 for measuring an optical characteristic of a specimen arranged to close a measuring opening and is used together with a spacer 24. Accordingly, such a calibration device 21 can perform more accurate white calibration by preventing formation of an interference pattern by the spacer 24.
