<p>PURPOSE:To constantly smooth the elevation of a base by composing a control means so that the whole carried articles can be completely housed in their housing shelve with the base slightly risen with a first drive means under the drive of a second drive means. CONSTITUTION:The overall placing of carried articles on a carrying body 2, when a base 1 is located at a reference position, causes a drive means 3 to be put in a first (or second) drive condition responding to a placing signal under the control of a control means 8 to rise (or lower) the base 1, and to be released from the said drive condition responding to the occurrence of a stage signal to stop the base 1. Concurrently with this, a drive means 4 is put in a drive condition under the control of a control means 8, and also a carried article is carried and housed in a housing shelf faced to the stopped position of the base 1 with the carrying body 2. Following this, the disappearance of the placing signal causes the drive means 3 to be put in the first drive condition for a short time under the control of the control means 8 to slightly rise the base 1 to completely house the whole carried articles in their housing shelve in cooperation with the drive means 4.</p> |
