A divider circuit includes: a register which is configured of an even number of bits and in which a dividend data is stored. A shift operation section is configured to acquire a data stored in an upper bit portion of the register when the even number of bits of the register is equally divided to the upper bit portion and a lower bit portion, as a quotient data when the dividend data is divided by a maximum of a divisor data which can be expressed by a half of the even number of bits of the register.

Divider circuit and division method

A collection device includes: a collection container that collects output material; a storage box that is opened upward to store a lower part of the collection container; and a support member that is fixed to a housing and supports the storage box so that the collection container is stored in the storage box and is freely drawn to the outside of the housing. The collection container includes a handle located frontward in a pulling direction and at an upper part of the collection container. The storage box includes a notch formed in a rear surface in the pulling direction. When the handle of the collection container is pressed backward in the pulling direction, a part of the collection container, which part is located backward in the pulling direction, protrudes from the storage box through the notch, so that the collection container inclines backward in the pulling direction.
